Title: Optical disk medium and its clock forming device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/24082
Filed: 1994-01-20
Abstract: PURPOSE:To make the crosstalks from adjacent tracks uniform and to record information at a specified recording density by setting the meandering periods of the track grooves at a specified angle viewed from a central point regardless of positions where the track grooves are formed. CONSTITUTION:All of the track grooves 1 of an optical disk medium are so formed as to meander at the equal interval periods thetak and, therefore, the unification of all the meandering periods to the same phase is possible. Then, the influence of the crosstalks from the adjacent tracks is made constant and eventually, the meandering of the tracks is stably detected even if the track pitch is narrowed. However, the meandering periods are longer nearer the outer periphery and, therefore, the number of equal division is made larger nearer the outer periphery in such a case. Consequently, the execution of recording at the equal density for the inside and the outside is possible.
